摘要：

(Figure Presented) It's logicall A set of DNAzyme-based Boolean logic gates consists of a series of supramolecular structures (see picture). Two metal ions (Mg2+ and Pb2+) act as inputs and gold nanoparticle (AuNP)/ DNA probes as output reporters for colorimetric detection. Fast performance of the logic system at ambient temperature is achieved. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
